Da Vinci's mischief: xylem conduits in the stems of woody plants do not furcate

open access: yesNew Phytologist, EarlyView.
Summary The hydraulic architecture of plants is often modeled as a ‘furcating’ network, in which xylem conduits proliferate in number toward the stem apex, analogous to animal circulatory systems. Yet whether furcation actually occurs within woody stems remains untested, despite major implications for carbon costs and hydraulic efficiency.

Weaponizing Kinship: A Demographic Analysis of Bereavement in the Colombian Conflict

open access: yesPopulation and Development Review, EarlyView.
Abstract The ongoing Colombian armed conflict has produced widespread homicides and enforced disappearances, as armed actors used violence to terrorize communities and consolidate power. Family bereavement—one of the most pervasive and enduring consequences of this violence—remains critically understudied from a quantitative perspective.

Humanism at the Council of Constance. Diego de Anaya, Classical Manuscripts and Education in Salamanca

open access: yesRenaissance Studies, EarlyView.
Abstract Due to their prolonged and multicultural nature, councils functioned historically as hubs for the exchange of ideas, discourse, diplomacy and rhetoric, reflecting broader cultural trends. In the Middle Ages, no international forums were comparable to ecumenical councils, where diverse and influential groups from various regions convened to ...

Pan‐European Fragile Populations Cohort for COVID‐19: What Worked, What Didn't, and Lessons Learned

open access: yesTransplant Infectious Disease, EarlyView.
ABSTRACT The COVID‐19 pandemic exposed the vulnerability of immunocompromised hosts and the scarcity of evidence guiding their management. Within the European Horizon 2020 ORCHESTRA project, a multinational consortium connected existing and new cohorts to harmonize data, laboratory methods, and clinical expertise across fragile populations. The fragile

The Reactive Extrusion Cationization of Starches as a Novel Physicochemical Surface Modification Method

open access: yesBiopolymers, Volume 117, Issue 3, May 2026.
Native starches from different botanical sources were cationized by reactive extrusion using 3% glycidyltrimethylammonium chloride (GTAC). The process, performed under controlled thermal zones, promoted the incorporation of quaternary ammonium groups onto the starch backbone.
